Cantabri

The Cantabri were a confederation of Celts that inhabited northern Spain.

History
The Cantabrians were from the city of Aracillum (present-day Aradillos, Spain), and they fiercely resisted both Carthage and the Roman Republic. During the War of the Second Triumvirate, the Cantabri established a trade agreement with Octavian's Rome, as they were both hostile to Lepidus' Rome. The Cantabri took advantage of the situation to conquer much of Marcus Aemilius Lepidus' lands in Spain, including Toletum (Toledo).
